PAPER-FEEDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 61 1,282, dated September 27, 1898.

Application filed September 27, 1897- Serial No. 653, (N0 model-3 T0 at whom it may concern.-

Be it known that I, JOHN H. RUSSELL, of Amsterdam, in the county of Montgomery, in the State of New York, haveinvented new and useful Improvements in Paper-Feeding Machines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to paper-feeding machines, particularly those wherein thick pa-' per, as sheets of strawboard, are fed successively from a pile; and the object is to feed the board from the top of a pile automatically to another machine-as, for instance, a lining-machine.

To this end my invention consists in the combination, with the frame, of blocks or followers movable vertically in the parts of the frame, feed-rollers between two of the blocks, a rod extending between the other pair of blocks, supporting a swinging arm, means connected to the said arm for engaging the upper sheet of the .pile and pushing it between the feed-rollers, a shaft below the said rod between the blocks, a cam on the shaft to operate the swinging arm, and gearing between the said shaft and one'of the feed-rollers; and my invention consists in certain other combinations of parts hereinafter described, and specifically set forth in the claims.

In the drawings hereto annexed and forming a part of this specification, Figure 1 is a side elevation of my improved paper-feeding machine. Figs. 2 and 3 are side and plan views, respectively, of the end of one of the side bars of the conveyer connected With the end of the lining-machine. Fig. 4 is a horizontal sectional view of the feeding apparatus, taken on line .90 0c of Fig. 1. Fig. 5 is an enlarged vertical sectional view of the apparatus, taken on line 3 z of Fig. 4. Fig. 6 is an enlarged plan View of the central portion of the feeding devices, taken below the frame. Figs. 7 and 8 are side and plan views, respectively, of the gripping means for the blocks or followers in the posts. Figs. 9, 10, and 11 are lower side, end, and sectional views, respectively, of the paper-feeding block nearest the feed-rolls, Fig. 11 being a sectional view taken on line as 00 of Fig. 9. Figs. 12 and 13 are side and lower side views of the pushing device which engages the edge of the board, and Fig. 14 is a longitudinal vertical section of the device shown in Fig. 13.

Referring specifically to the drawings, A is the base of the framework supporting the table A, on which the pile of paper or boards B lies.

0 and O are the corner-posts, 0 extending higher than C, and A are the beams connecting the posts together at the top. Each of the corner-posts is divided transversely throughout its length to provide guideways for followers or sliding blocks D D. The followers D are connected together by a bar E and a pair of paper-feed rollers F and F, arranged one below the other, between which the upper sheet of the pile of boards passes when pushed to the right by the pushing device. The followers D are connected together by a shaft G, carrying at its center an eccentric or cam G, which operates or swings a hanging bar H and a rod H above and parallel with said shaft, from which the bar H is suspended. Each of the followers is connected at its upper and lower end with the opposite ends of chain a, which passes around sprocket-wheels b b at the upper and lower ends of the post. WVeights o CL are shown on the chains a a to partially counterbalance the parts mounted on the blocks D and D.

b is a sprocket-Wheel on one of each pair of posts, provided with a crank b" for operating the chain and raising the followers. The

sprocket-wheels b b on the top of the frame are.

secured on the same shaft 0. Consequently the followers on opposite sides work together. The followers in the posts 0 are caused to move with the followers in posts 0 by means of a gripping-bar I, which extends between the followers on one side of the machine and is pivoted at one end to the follower D and at the other end to the bar I near the follower D.

Each of the corner-posts on the side of the machine having the bar I has a vertical rod J, extending the full length of the post on the inside thereof. The said rodsJ are stationary and pass through projections j on the followers. The end of the bar I, pivoted in the projectionj of the follower D, is provided with a heel or corner which impinges upon the rod J and prevents the falling of the follower D when the follower D is at rest. The means for lowering the followers D is substantially the same as those described for lowering the followers D, and will be hereinafter referred to.

(Z (Z are adjustable guides on the posts 0 and O on one side of the machine, against which the pile of boards 13 is placed.

Hinged to the cross-bar E is a pair of converging bars 6 e, which slightly incline toward the opposite side of the pile and are joined together at their ends by a rectangular piece j, which rests upon one or more rollers on the pushing and separating device K below. The said pushing device K is provided with a hinge K on its inner end, which is coupled to an arm f, that is in turn pivoted to a lug or projection g on the lower side of a board g, having ribs g, on which the pushing-block h for the paper slides. The block it is moved in the rearward direction by a small pin 10, projecting from the lower side of the board 9, striking the end of the block it during the rearward movement of the said board. Said pin 10'' is shown in Fig. 10 of the drawings. \Vhile engaging and pushing forward a blank, the pivoted ribs w are held in a vertical position by the small projections or blocks 2, secured to the lower side of the block it.

The separating and pushing device K, the board g, and the connecting-arm are moved together and rcciprocated to carry forward or push the upper sheet of paper or board from the pile between the feed-rollers F and F, and these carry the sheet still farther to the conveyer L, which is provided with a series of pairs of feed-rolls and guides between them to keep the sheet fiat during its transit to the lining or other machine, on which one end of the conveyor rests. As soon as one sheet is pushed between the rolls F and F the pushing devices are moved backward preparatory to pushing forward another sheet. Immediately after one sheet has passed the feed-rolls another sheet is pushed between them, the operation being repeated until the pile is exhausted.

The pushing devices are connected by a bar H with the lower end of the hanging bar H, and this bar is oscillated by a projection on one side of the cam striking a pair of projections alternately on one side of the bar H. The cam is rotated by the shaft in the direction of the arrow, (shown in the figures,) and when its projection 'i strikes the lower projection on the swinging bar H the latteris moved back preparatory to separating the edge of the upper sheet from the pile and pushing it forward. Having accomplished this, the projection ileaves the said projection 2 on the bar and is turned by the shaft G to engage the rear side of the upper projection t", which causes the wedge or point Z on the pushing device K to enter between the upper sheet and the sheet below, thus separating them,

and when the stop Z strikes the edge of the upper sheet it is pushed forward and the opposite edge enters between the feed-rollers F and F.

In Fig. 1 a simple form of pushing device K is shown; but in Figs. 5, 11, 13, and 14 the device is shown provided with a sliding piece m, which is connected to the device by dovetailed guide and a coiled spring 172. The sliding piece is provided with a vertical bolt 42, which enters the plate having the point Z. This bolt is operated by a pivoted trigger 0, which is engaged by asmall spring 0, that forces the bolt inward and locks the sliding part m to the upper part having the point Z. When the entire pushing device has been moved forward sufficiently to cause the point I to enter between the top sheet and the lower sheets, together with the beveled end of the part m, the trigger o strikes against the side of the pile of sheets of paper, drawing downward the bolt 01 from the said upper part and unlocking the part 971. lVhen, however, the cam G has turned sufficiently to disengage the upper projection t' on the swinging bar H, the spring on causes the upper part to move backward quickly toward its outward position. \Vhen the projection on the cam G engages the lower projection 'i on, the swinging bar II, the movement of the part K is completed. The spring m maybe dispensed with, the part K being moved back by the cam engaging the lower projection 2'. By means of this modification much friction is overcome that attends the operation of the device shown in Fig. 1 due to moving the device on the rough paper. With the part m it enters with the point Z but a short distance and is arrested in its movement by the trigger o striking the pile and remains in this position while the upper part slides smoothly upon it while feeding the sheet.

The feeding devices are lowered with the pile of paper by means of a gripping-arm I, pivoted to the projeetionj on the follower D and having the upper cornerj of its end impinging against the vertical rod J. The said arm 1 extends inward over the center of the pile of paper and rests on an arched crossbar 6, extending between the bars 8 e.

The operation is Very simple. \Vhen a sheet is withdrawn from the pile by the feedrollers, the bars 6 c and 6 fall the distance corresponding to the thickness of one sheet. This allows the end of the bar I to fall correspondingly, removing the eornerj slightly from the rod J, allowing the feeding devices to drop slightly; but as soon as the followers D have dropped the same distance that the end of the bar I fell the grip is again applied to the bar J and the followers held from falling farther until another sheet is drawn from the pile. The other gripping-bar I being pivoted to the bar 1, as shown at p in Fig. 8 of the drawings, the followers D fall at the same time or immediately after the followers D.

The conveyor L consists of a frame comprising side bars, each having a central slot extending lengthwise the bar, pairs of feedrollers q equal distances apart between the side bars and adapted to turn in bearings r, secured on the inside of the bars, and a'series of parallel guides 5, arranged side by side between the pairs of rollers to keep the sheets flat while passing between the rollers. The guides are formed of strips of Wood secured equal distances apart at their centers to crossbars 5, extending between both the upper and lower sides of the side bars. The upper and lower guides s s are parallel with each other are separated sufficiently to allow the sheet to pass freely between them, and have their ends beveled properly to receive the sheet easily as it comes from the rollers. Each pair of feed-rollers is geared together by small cog-wheels t at one end of the rolls. The lower shafts of the feed-rolls are extended through the side bar 011 one side of the conveyer and are provided each with a pair of small sprocket-wheels t, and these wheels are connected together by chains t, (indicated by broken lines in Fig. 4,) so that they are driven together synchronously with the feed-roller F. The feed-roller F is provided with a sprocket-wheel and chain F, which drives a large sprocketwheel G on the shaft G.

The driving belt or chain N is connected to a sprocket on the last lower feed-roll shaft of the conveyer and receives motion from a sprocket (not shown) 011 the lining-machine M, the end of which is shown in Fig. 2 of the drawings. The rear ends of the side bars of the conveyer are hinged to the followers D, so that they will rise and fall with them. The opposite end of the conveyer is broadened by means of offsets L in the side bars to receive the end of the lining-machine M between them. The offsets rest on rollers u, mounted on the sides of the frame of the lining-machine, so that said conveyer can move longitudinally while the conveyer is raised or lowered. The upper roller of each pair of feed-rollers is made yielding and adjustable to a limited extent by any suitable and well-known means, 42 being the screws for adj usting them. At the commencement of the movement of the device K to the right the part h remains stationary; but after the point Z enters the pile below the upper sheet and when the edge of this sheet strikes the stop Z then the lug g on the lower side of the board g engages the plate h, and the latter is moved, with the device K, the balance of the movement to the right.

The lower side of the block 77. is provided with pivoted ribs 20 containing teeth w,which engage the sheet to carry it forward. During the backward movement of the block it these ribs turn in their bearings and incline so that the sheet is not hindered in its forward movement. As soon as the lug g strikes the end of the block it to carry it forward the ribs assume their vertical position, and this is aided by the small springs to, engaging the central parts of the sides of the ribs, as indicated in Fig. 11.

I do not desire to be limited to the precise form of construction of the parts shown and described, as they may be modified without departing from my invention.
